## Summary
- Increase MAX_TOOL_CALL_STEPS from 25 to 50 to allow longer multi-step
tasks
- Add step limit detection to track total steps across all passes
- Show a clear `<dyad-step-limit>` message when the limit is reached,
instructing users to send "continue" to resume
- Create DyadStepLimit component for displaying the pause notification

Fixes #2754

## Test plan
- Run the local agent and perform a task that requires many tool calls
- Verify the agent pauses at 50 tool calls instead of 25
- Verify a clear message is shown explaining why it paused and how to
continue
- Type "continue" to verify the agent resumes working
